Cant Join Domain ater changing PC name

[ajrey]

Hello! I got new PC's and replaced the old with the new PC's. Naming the PC's with the user's name to identify easier in network the workstations. Now...I cant have 2 PC's in domain with same name. So I changed the PC name of the old PC, and when I try to join domain, says "domain could not be contacted or does not exist" Why is this? I have enough ip addreses available in DHCP. I ran ipconfig /all and the info i get is correct. Ej(ip address, DNS server address, Gateway address) so why Cant I join domain?

Any Ideas?

Did you originally set-up the old pc's with the same admin account? If not, Windows sometimes has problems with access rights. If the user account has different access rights, this can happen.
Easiest fix, is to delete old computers from Active Directory Users and Computers, and add new computers to the domain.
